efficacy, safety and cost-efficacy of a pre-emptive genotyping strategy in patients receiving statins

Conditions: Cardiovascular Diseases; Dyslipidemias; Statin Adverse Reaction; Pharmacogenic Myopathy

Summary: this is a phase iv multicentre adaptive single-blinded randomized clinical trial if preemptively genotyping populations at risk of cardiovascular disease susceptible of receiving high or moderate doses of statin therapy is efficacious, cost-efficacious, and feasible within the spanish national health system when compared to the current standard of care. this trial is nested within the ipharmgx master protocol

this is a nation-wide, multicentre, randomised, controlled, and adaptive phase iv clinical trial that aims to assess the efficacy and cost-efficacy of pre-emptive pharmacogenetic testing strategies, including those impacted by genetic variants associated with adverse drug reactions (adrs) or limited efficacy. populations at high-risk of developing clinically relevant outcomes will be enrolled in nested trials within this master protocol. the clinical trials will evaluate the efficacy and cost-efficacy of pre-emptive genotyping by defining a drug-gene-endpoint triad. study subjects will be pre-emptively genotyped and, if found to have an actionable gene variant, randomly allocated to either a test group where guideline-based treatment modifications will be initiated or a control group that will be managed according to healthcare provider standard of care (soc). subsequently, subjects will be prospectively followed at prespecified timepoints. detailed information on drug-gene-endpoint triads, allocation schemes, and follow-up visits will be provided in each of the subprotocols. a data monitoring committee (dmc), composed of physician experts, will be appointed for each nested trial to review the data on an ongoing basis, ensuring the safety of participants and scientific validity of the study.
